Caring For Your Pool Heater - Waterco HEAT PUMP SWIMMING POOL HEATERS Owner's Manual

Protection Devices
The integrity and performance of your pool heater and its components is protected by controls. In normal use, the
Waterco unit should never reach the thermal protection level. However, should it happen, you should verify your
operating conditions as described below.
The Waterco unit is designed to operate with a minimum water circulation of 113lpm. The high pressure switch
will shut off the compressor if there is not sufficient water flow through the unit. Check for dirty filters, clogged
skimmers or the bypass valve position. They are usually the cause of this condition.
The Waterco unit also has a built-in water pressure switch that will interrupt the operation of your unit should
water circulation through the unit stop. If there is still a demand for heat, turn on your pool pump and the heater
will start up once the normal water flow is re-established.
Your heat pump pool heater features other protection devices that could stop the unit:
High pressure cut-out switch,
Low pressure cut-out switch,
Thermal protection for the compressor and the fan motor
Adjustment of the bypass valves
The adjustment may vary according to the pool pump size and the climatic conditions.

CARING FOR YOUR POOL HEATER

The Waterco pool heater has been specifically engineered to give you many years of satisfaction. To clean the
plastic surfaces use soapy water and a clean soft cloth. Never use solvents or abrasives.
The dirt collected in the evaporators can be removed with a gentle water spray and the use of a soft brush. Be
careful not to damage the aluminum fins. Do not use a pressure washer to clean the evaporator as it can damage
the fins.
Usage Of Chemical Products
IMPORTANT
Adequate water circulation and the proper use of chemical products is absolutely necessary to protect your
family's health and your pool heater.
The following are essential water quality readings and must be maintained at all times.

Winterising
VITAL
!
Set the water temperature setting to OFF. Turn the pool heater breaker OFF. If the unit is stored in a place where
the temperature drops below the freezing point of 0˚C, it is mandatory that the water accumulated in the unit
be drained completely before freezing weather prevails. The water piping MUST be disconnected to drain
the heat exchanger in preparation for winter. Once the piping is disconnected, the unit MUST be drained of all its
water by tipping it (75˚). It is recommended to flush the inside of the heat exchanger with the garden hose and to
drain the unit again. Using 2 pool return caps, block the water in and water out to prevent any intrusion. Do Not
leave the water piping connected to the heater over the winter.
DO NOT put anything under the water connect ions of the unit to lift it up. This can keep water inside the heater
and cause freezing damages.
Unit may be covered for the winter. The use of a material that will allow air to go inside the heater is
recommended.
It is also possible to fill the heat exchanger with pool anti-freeze only, but ensure that the anti-freeze contains an
elevated pH to prevent corrosion. This is optional and requires appropriate hardware.
